Using more recent climate data


Recommended Posts


The climate data that PVSol allocates to most locations in the Netherlands is quite outdated (1990-2010). However, the radiation has significantly increased last years. Therefore, the estimated yield could be underestimated by PVSol. Would it be possible to use more recent climate data that also incorporates the last 10 years, for example with a range from 1990 untill 2020? And, if possible, would you recommend to do this?

Hi Reint,

this is a frequently asked and discussed topic. See for example here:

At the moment, our climate data provider doesn't have data with more recent time spans for the Netherlands. If you want to use more recent data, we would recommend downloading the TMY data from PVGIS (link is also in the post above).

Hope that helps,
